Title (EN) SPRING-DAMPED VEHICLE SEAT
(FR) SIEGE DE VEHICULE AMORTI PAR RESSORTS
Abstract: front page image
(EN)The seat (2) for vehicles, machines and the like, damped by means of one or more springs (8), may be set at a given initial level in view of different loads in order to optimize the available travel of the spring. At least one hydraulic jack (6) is supporting the spring(s) in order to allow easy and quick setting of the initial level. The seat is provided with a sensor (9) indicating the level of the seat and operating as the sensor of an adjusting device which controls the hydraulic jack, thereby providing for a given average level of the seat. The adjusting device operates for a short time in order to match the spring tension against the weight of a person sitting on the seat and, by means of valves (11) connects the hydraulic jack with a pressurized fluid (13) or with a return pipe until the displacement of the spring support brings the spring at its initial level. After the support is locked at its new position and the adjusting device starts to operate, the damping of the seat matches the new load.
(FR)Le siege (2) pour vehicules, machines ou analogues amorti au moyen d"un ou de plusieurs ressorts (8), peut etre ajuste a une hauteur de depart donne en fonction de differentes charges de facon a optimaliser la course disponible du ressort. Au moins un cylindre hydraulique (6) supporte le ou les ressorts de facon a permettre un ajustement rapide et facile de la hauteur de depart. Le siege est muni d"un capteur (9) indiquant la hauteur du siege et fonctionnant comme palpeur d"un organe de reglage qui commande le cylindre hydraulique pour obtenir une hauteur moyenne determinee du siege. Pour pouvoir adapter la tension du ressort au poids d"une personne occupant le siege, l"organe de reglage entre brievement en action et grace a des soupapes (11) met en communication le cylindre hydraulique normalement bloque avec un fluide sous pression (13) ou avec un conduit de retour jusqu"a ce que le deplacement du support de ressort amene celui-ci a sa hauteur de depart. Apres le blocage du support dans sa nouvelle position et apres le declenchement de l"organe de reglage l"amortissement du siege est adapte a sa nouvelle charge.
